Air purifier's corona electrode

The utility model belongs to the technical field of the air purification technique and specifically relates to an air purifier's corona electrode. It includes the electrode support pole that an axis of following an influence electricity polar line section of thick bamboo distributes, has cup jointed two at least insulating position sleeves on the electrode support pole, just is located on the electrode support pole and has still cup jointed a foil between two adjacent insulating position sleeves, and foil is connected with electrode support pole electricity, and the heterocharge interval thatforms between foil's each point of discharge and the inner wall of an influence electricity polar line section of thick bamboo is impartial. The utility model discloses can set for foil's geometry according to given high voltage power supply's dynamic operating range, at this in -process, only need guarantee that the heterocharge interval is impartial, and corona electrode work all the time be higher than corona inception
